I have found that by loosely closing up the QR with the wheel slightly offset towards the NDS, I can then get the chain tug to pull the wheel straight, and then really tighten up the QR’s again. The chain tug needs to pick up the tension, not the QR’s. It also helps really tension up the chain nice and tight. Having said that, I have noticed that the chain is significantly stiffer prior to riding. I have taken to doing a bit of pedal stomping up a hill or two before tensioning the chain again, then it seems to keep tight for the rest of the ride. I can only guess the lube thickens up(?)
